Christian Lawson-Perfect explains himself:
- I can never remember π past 3.14159..., and typing "digits of pi" into Google doesn't always lead you straight to a usable listing, so I wanted a place I could go to to easily get at least the first few hundred digits.
- Ever since I discovered it, I've wanted to write an implementation of an unbounded spigot algorithm for π.
- I enjoy buying novelty domain names.
- It was a fun thing to do for π day.
I'm a total sucker for this kind of thing.
